Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The disclosed invention generally pertains to the field of fuel accounting jet fuel, and more specifically, to a system and method for verifying that fuel to be paid for has in fact been received and dispensed to an organization's designated equipment.

2. Description of the Related Art

There has been a long felt need among organizations operating aircraft to better record, validate, and verify the amount of fuel dispensed from a fueling agent into an aircraft. Typically, an organization's method for collecting such data is paper-based fuel tickets provided directly by the fueling agent at the airport where the aircraft is refueled. In many cases, the fuel tickets are received at several different airports and are sent to a central location and manually entered into an accounting system. This process can lead to key entry errors, lost tickets, and critical time loss waiting for fuel tickets to arrive at the central location to be processed. This problem is even more prevalent at many International airports where organizations may have fewer personnel on hand to handle fuel tickets and make sure they are properly processed.

In addition, these organizations are relying on data supplied by the fueling agent without any independent data to verify what is received from the fueling agent is accurate. This can lead to inaccuracy in fuel dispensed, i.e., uplifted, into aircraft and added fuel expense, having an enormous impact on the organization's profitability. Fuel expense is a major cost for organizations operating aircraft as demonstrated in statistics reported by the United States Department of Transportation Bureau of Transportation Statistics stating airline's fuel uplifted for 2006 was over seventeen billion gallons at an expense of thirty-four billion dollars. At times when fuel prices increase, these inaccuracies will become more of a factor in an organization operating aircraft's profitability.

Attempts have been made to better record fueling data as disclosed in U.S. Pub. No. 2005/0267673 entitled “Multiple Fueler Operations for Fuel Information Messaging System.” This application teaches a fuel management system for fueling aircraft that enables multiple fueling agents to service an aircraft simultaneously. The system tracks and reports the amount of fuel provided by each fueling agent for determination of the total amount of fuel dispensed to the aircraft. Each fueling agent reads the starting and ending fuel gauge or dipstick readings as well as the amount of fuel dispensed and uses a handheld Fueling Agent Client Device to transmit fuel gauge readings and the amount of fuel dispensed for the purpose of producing a fuel ticket in hard copy or electronic form for delivery to the aircraft pilot. Though the amount of fuel dispensed into the aircraft is validated, it is validated based on data provided by the fueling agent(s). In addition, the end result is the production of a fuel ticket that does not address the need for front-end data capture. Thus, in the application, there is no front-end data capture of a fueling event and no information flow for reporting the amount of fuel dispensed into an aircraft that is not under the control of the fueling agent(s).

Likewise, U.S. Pat. No. 6,119,058 entitled “Method and Systems for Controlling the Service for an Aircraft” teaches a system with a central computer that receives information from the administrative database of the airport for purposes of servicing the aircraft while parked at an airport and downloads this information to several local computer units that are stationed in servicing units. This information can then be used by the servicing units to automatically service the aircraft such as refueling. Once the servicing is complete, the local computer unit transmits information received during servicing back to the central computer. In the case of refueling, the central computer can then calculate the amount of fuel dispensed and create a fuel ticket. Though the patent addresses a concern of better servicing aircraft by minimizing the chance for human error, it still does not address the airlines concerns over better fuel accounting and affording them more control over verifying what fuel is dispensed into their aircraft.

Thus a need in the art exists to facilitate the front-end data capture and validation of a fueling event and more specifically the front-end data capture and validation of a fueling event by the organization operating the aircraft via a data pathway not under control of a fueling agent. In addition to verifying that fuel to be paid for has in fact been dispensed for better fuel management, such a system and method would ideally reduce the amount of personnel needed, facilitate timely fuel data, reduce missing fuel tickets, increase airport accountability, increase fuel data integrity, increase visibility of timely fuel data to such business functions as accounting, inventory management and procurement, increase accuracy of fuel related planning decisions, provide more efficient and accurate data capture, or combinations of one or more of these objectives.

Yet, in other embodiments of the invention, the determining whether the fueling information matches to corresponding flight information is performed based on one or more of origin airport, flight number, tail number, gallons of fuel, or date in respective to the fueling information and the flight information. Still, in other embodiments of the invention, the releasing of a fuel event for approval after it is determined a fueling event did occur from further investigation though initially the fueling information did not match to the corresponding flight information is performed by a person other than the person key-entering the fueling information into a computer system.

In addition, in various embodiments of the invention, a method providing an organization operating aircraft with the capability to verify fuel uplifted over a selected period of time comprising the method discussed directly above, wherein steps (a) through (h) are repeatedly performed for all fueling events over a selected period of time, further comprises the steps of: (i) following last performance of step (d), step (f) or step (h), determining a first total fuel amount by summing up fuel amounts for all of the fueling events released for reconciliation for the period of time; (j) determining whether the first total fuel amount reconciles with a second total fuel amount issued by a fueling agent for the period of time; (k) if the determination in step (j) establishes that the first total fuel amount does not reconcile with the second total fuel amount for the period of time, contacting the fueling agent to resolve inconsistency; and (l) if the determination in step (j) establishes that the first total fuel amount does reconcile with the second total fuel amount for the period of time, releasing to accounting the fueling events released for reconciliation for the period of time.

DETAILED DESCRIPTION OF THE INVENTION

The present invention will now be described more fully with reference to the accompanying drawings, in which some, but not all embodiments of the invention are shown. Indeed, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.

Brief Overview

Various embodiments of the present invention provide systems and methods for fuel accounting and in particular verifying that fuel to be paid for has in fact been dispensed into equipment. In particular, various embodiments provide systems and methods to enable an organization operating aircraft to verify that a particular fueling event has occurred. One such embodiment involves the organization operating the aircraft receiving a first fuel amount data for a fueling event via a data pathway not under control of a fueling agent and a second fuel amount data derived from the fueling agent for the fueling event. The first fuel amount data is compared with the second fuel amount data to determine whether a fueling event has occurred and whether to release the first fuel amount data for reconciliation with the fueling agent.

Furthermore, various embodiments provide systems and methods to enable an organization operating aircraft to verify fuel uplifted for a selected period of time. One such embodiment involves repeating the steps to verify a fueling event has occurred for each proposed fueling event over the period of time and if it is determined that the fueling event did occur, releasing the fueling event for reconciliation. Also generating a first total fuel amount data by summing the fuel amount data related to the fueling events released for reconciliation for the period of time and receiving a second total fuel amount data from the fueling agent for the period of time. The first total fuel amount data is compared with the second total fuel amount data to determine whether to release to accounting the first fuel amount data associated with the fueling events released for reconciliation.

Lastly, various embodiments provide systems and methods to enable an organization operating aircraft to verify fuel inventory for a selected period of time. One such embodiment involves receiving inventory receipts for fuel purchased over the selected period of time from the fueling agent, in addition to bills-of-lading issued from a fuel supplier related to the fuel purchased over the period of time. The inventory receipts and bills-of-lading are summed to generate a first total inventory amount data and second inventory amount data, respectively, and are compared to determine whether to release to accounting the supplier invoices related to the second inventory amount data.

Fueling Event Verification Method

An exemplary fuelingevent verification process100 according to various embodiments of the invention is shown inFIG. 1. Various embodiments may begin with an aircraft stopping at an airport for refueling and the aircraft is fueled by a fueling agent, as shown inStep101. For example, in one embodiment, the fueling agent may be a fixed base operator (“FBO”). Specifically, fuel farms exist in various parts of the world in which organizations operating aircraft purchase jet fuel from a supplier, such as Shell or Chevron/Texaco, and the purchased fuel is delivered to the fuel farm along with a bill-of-lading. Therefore, the fuel farm consists of a number of organization's fuel consolidated into tanks in which an organization owns a percentage of the fuel inventory held in the tanks based on their individual fuel purchases. In addition, the FBO serves as an onsite vendor that manages the fuel inventory and typically pumps the fuel into the aircraft. Thus, inprocess100, the FBO drives a fuel dispenser truck out to the airport and processes fuel, i.e., uplifts fuel, into the aircraft sitting at the airport.

However, it should be understood that various other embodiments do not necessarily involve a fuel farm run by a FBO. For example, other embodiments may be practiced in conjunction with an independent fueling location wherein organizations operating aircraft do not store an inventory of fuel in consolidated tanks, but simply, the fuel inventory is owned by an independent organization who sells the fuel. Therefore, it should be understood that the fuel farm managed by an FBO is simply used as an example of various embodiments throughout this document in order to illustrate the invention.

Next, inStep102, the fueling agent reads the amount of fuel dispensed into the aircraft and provides fueling information for the particular fueling event to the organization operating the aircraft. In one embodiment, this can be accomplished by the FBO reading the beginning and ending meter readings on the fuel dispenser truck or reading the total number of gallons dispensed and producing a fuel ticket, either electronically or manually, and presenting the fuel ticket to an airline employee at the airport. In many instances, the fuel ticket will provide additional information such as origin airport, flight number, tail number, date, or various other information related to the fueling event. In an alternative embodiment, the fuel ticket information is transmitted by radio frequency (“RF”) technology to the airline's computer system from a hand-held device or directly from the fuel dispenser truck. The fuel ticket data can be entered into the airline's computer system by several manners such as key-entering the data by an airline employee, electronic transmission over a communication network (e.g., Internet or private network), or by RF technology. For example, the airline employee may be provided with a Ticket Add interface in which the employee enters the information found on the fuel ticket and clicks the “Save” button.

In conjunction, atStep103, the organization operating the aircraft receives or accesses flight information by a data pathway not under control of the fueling agent. In various embodiments, the organization receives or accesses the flight information via a number of different data links. For example, in one embodiment, this step can be accomplished by receiving flight information directly from the aircraft by downloading flight record data from the aircraft's Aircraft Communications Addressing and Reporting System (“ACARS”) through electronic or wireless technology, or by flight data coupons into the airline computer system. In other embodiments, the organization receives or accesses the flight information as aircraft data through various other systems such as the legacy flight service system for the airline. In addition, various embodiments may access or receive information such as flight number, airport, or date from the airline's system used to schedule all aircraft over a communication network (e.g., Internet or private network). In other embodiments, the organization receives or accesses the flight information either locally or remotely from a database, data warehouse, file, or other storage device of the airline computer system. For example, in one embodiment, equipment information and aircraft tail numbers may be stored in a database in which such information is received or accessed and used for validation purposes. Lastly, various embodiments may access or receive industry information from public references such as the International Air Transport Association (“IATA”) and the Federal Aviation Administration (“FAA”) that may be used for validation purposes.

After obtaining both the fueling information from the fueling agent and flight information via a data pathway not under control of the fueling agent, a comparison between the two sets of information is performed to look for a match, as shown inStep104. This step can be accomplished in a number of ways as will be apparent to one of ordinary skill in the art. For example, in one embodiment the two sets of information can be manually compared by an airline employee or in another embodiment the two sets of information are entered, received, or accessed by the computer system and the system performs the comparison and determines whether a match exists. Comparison criteria may include many different types of information such as origin airport, flight number, tail number, date, gallons of fuel, or any combination of this information. In addition, various embodiments may employ various tolerance levels for the various criteria.

If a match is found to only one flight, the fueling event is made available for reconciliation with the fueling agent, as shown inStep108. In various embodiments, the fueling information is simply stored electronically and is ready for reconciliation. In other embodiments, this simply entails paying the invoice for the fueling event. In other embodiments, the fueling event is made available to verify the amount of fuel dispensed for the fueling event with the fueling agent. For example, the fueling event data for a period of time can be supplied in a report through various channels such as a website, a monitor, an e-mail, or a facsimile to the FBO or airline personnel to verify the fuel dispensed for each fueling event with other data supplied by the FBO.

If more than one flight is found to match, no flight is found to match, or a flight is found to only partially match, e.g., some of the criteria match while other criteria does not match, the particular fueling event is further investigated to determine whether it occurred or not, as shown inStep105. The investigation can be performed in one embodiment by an airline employee further looking at the fueling information received from the fueling agent and matching it manually to flight information gathered from various aircraft. In another embodiment the computer system can further conduct this investigation by receiving or accessing additional flight information, such as departure time, arrival time, out of the gate time, or into the gate time and comparing this information to the fueling information received from the fueling agent. Or in an alternative embodiment, the computer system can use a secondary set of criteria to establish a match. For example, the primary set of criteria can be to match flight number, tail number, date, and gallons of fuel being within ten gallons. If a match is not found using the primary criteria, the computer system resorts to a second set of criteria such as origin airport, departure time, date, and gallons of fuel being within ten gallons.

If it is determined from the investigation that the fueling event did not occur, the fueling event is prohibited from further processing, as shown inStep106. In one embodiment of the invention, this step can be carried out by an airline employee investigating the source of the fuel ticket and deleting the fuel ticket in order to prohibit payment or in another embodiment a computer system can put the fuel ticket on hold, produce a report listing the discrepancy, or automatically delete the fuel ticket from the system to prohibit payment.

If it is determined from the investigation that the fueling event did occur, the fueling event is approved inStep107 and made available for reconciliation with the fueling agent as shown inStep108. In one embodiment, this step is carried out manually by an employee of the airline who was not involved with entering the fueling information. This ensures that a second person reviews the data entered by the first person, providing greater assurance that the fueling information was accurately entered into the computer system. In another embodiment, the fuel ticket is simply released automatically by the computer system.

Fuel Uplifted Verification Method

An exemplary fuel upliftedverification process200 according to various embodiments of the invention is shown inFIG. 2. Various embodiments may begin with determining a first total fuel amount for a selected period of time by summing up the fuel amounts from the fueling events released for reconciliation for the period of time, as shown inStep201. For example, in various embodiments, the first total fuel amount is found by summing the fuel amounts found on the fuel tickets released for reconciliation for the day. In one embodiment, the summing process can be performed manually by an airline employee summing up the amounts on the fuel tickets or in an alternative embodiment, the fuel ticket amounts may be entered manually or electronically into a computer system and the system sums up the amounts. In other alternative embodiments, a computer system can receive or access the fuel ticket amounts either locally or remotely from various sources such as a database, data warehouse, file, or other storage device and sum up the amounts to generate a total fuel amount.

In conjunction, atStep202, a second total fuel amount is issued and received or accessed for the selected period of time from the fueling agent. In one embodiment, for example, the FBO issues a total amount of fuel dispensed for the day and transmits the total to the airline via a communication network (e.g., the Internet or private network), phone, mail, e-mail, or facsimile. This information can be received or accessed either manually by an airline employee or received or accessed directly by a computer system. In another embodiment, the FBO transmits the FBO's ending fuel inventory for the day by similar channels.

The first total fuel amount is compared to the second total fuel amount to determine if the two amounts reconcile, as shown inStep203. In various embodiments, this comparison is performed in many different ways as will be apparent to one of ordinary skill in the art. For example, in one embodiment, the second total fuel amount received from the FBO is the FBO's ending fuel inventory for the day. In conjunction, the previous day's ending fuel inventory is received or accessed. In addition, the bills-of-lading from the FBO for the day are received or accessed and summed. Thus, an ending fuel inventory for the day is calculated by taking the previous day's ending fuel inventory, adding the bills-of-lading summed total, and subtracting the first total fuel amount. This calculated value is compared to the second total fuel amount to see if the difference between the two values falls within a predetermined tolerance. In various embodiments, this step can be performed manually by an airline employee or automatically by a computer system.

If the first total fuel amount and the second total fuel amount do not reconcile, the fueling agent is contacted to resolve the discrepancy, as shown inStep204. In one embodiment, this constitutes an airline employee contacting the FBO by phone, e-mail or by facsimile, for example, and discussing the discrepancy. For instance, the FBO may have erroneously included fuel dispensed into another organization's aircraft into the total amount of fuel dispensed for the day in which case resolving the discrepancy involves simply correcting this value. Once the discrepancy has been resolved, the process of verifying fuel uplifted for the time period is repeated.

If the first total fuel amount and the second total fuel amount do reconcile, the fueling events released for reconciliation for the period of time are released to accounting, as shown inStep205. For example, in one embodiment, the airline reconciles and validates the fuel tickets for the day using FBO distributed information and issues the fuel tickets to accounting either manually or through a computerized automated process.

Fuel Inventory Verification Method

In addition to verifying fuel uplifted, fuel inventory may also be verified. Thus, an exemplary fuelinventory verification process300 according to various embodiments of the invention is shown inFIG. 3. Various embodiments may begin with determining a first total inventory amount for a selected period of time by summing up the fuel receipts for the fuel that was received into inventory for the period of time, as shown inStep301. For example, in various embodiments, the first total inventory amount is found by summing the inventory receipts stated on an inventory statement received from the FBO on a daily basis. In one embodiment, the summing process can be performed manually by an airline employee summing up the receipt amounts or in an alternative embodiment, the receipts amounts may be entered manually or electronically into a computer system and the system sums up the amounts. In other alternative embodiments, a computer system can receive or access the receipt amounts either locally or remotely from various sources such as a database, data warehouse, file, or other storage device and sum up the amounts.

In conjunction, atStep302, a second total inventory amount is determined for the selected period of time. In various embodiments, the second total inventory amount is calculated by summing the bills-of-lading issued by the fuel supplier for the selected period of time. For example, in various embodiments, the bills-of-lading are received via a communication network (e.g., the Internet or private network), phone, e-mail, mail or facsimile directly from the fuel supplier or from the FBO and summed. In one embodiment, the summing process can be performed manually by an airline employee summing up the bills-of-lading amounts or in an alternative embodiment, the bills-of-lading amounts may be entered manually or electronically into a computer system and the system sums up the amounts. In other alternative embodiments, a computer system can receive or access the bills-of-lading amounts either locally or remotely from various sources such as a database, data warehouse, file, or other storage device and sum up the amounts.

Next, the first total inventory amount is compared to the second total inventory amount to determine if the two amounts reconcile, as shown inStep303. If the first total inventory amount and the second total inventory amount do not reconcile, the fueling agent is contacted to resolve the discrepancy, as shown in Step304. In one embodiment, this constitutes an airline employee contacting the FBO by phone, e-mail or by facsimile, for example, and discussing the discrepancy. For instance, a fuel ticket may have been erroneously prepared by the FBO in which case resolving the discrepancy involves simply correcting the bill-of-lading. Once the discrepancy has been resolved, the process of verifying fuel inventory for the time period is repeated.

If the first total inventory amount and the second total inventory amount do reconcile, the supplier invoices for the selected period of time are released to accounting, as shown in Step305. In various embodiments, this may be accomplished either manually or through a computerized automated process.

System Architecture

The fuel accounting system can be incorporated into an organization operating aircraft's system in numerous ways. In one embodiment, the fuel accounting system can be connected to a legacy system via a network (e.g., a LAN, the Internet and/or private network). In another embodiment the fuel accounting system may be a stand-alone system. The fuel accounting system can also receive or access data and communicate in various ways such as in various embodiments the data is entered directly into the system either manually or via a network connection. In other embodiments the data is received or accessed by communicating either to a local or remote system such as a database, data warehouse, accounting system, other module, file, or storage device.

FIG. 4 shows a schematic of asystem architecture400 that includes the fuel accounting system according to various embodiments of the invention. Generally, thesystem architecture400 is configured to access or receive and integrate various data to provide thefuel accounting system500 with the information necessary to validate fueling events, total fuel uplifted, and total fuel inventory. In several embodiments, this data is stored on various storage devices, such as a hard disk drive, a floppy disk drive, a CD Rom drive, a DVD Rom drive, a USB flash drive, or optical disk drive, for storing information on various computer-readable media, such as a hard disk, a removable magnetic disk, a CD-ROM disk, or a DVD-ROM disk. The various data may be stored on a single storage device or may be stored on separate storage devices. In addition, in various embodiments, this data may compose a database or simply be stored as a file or group of files.

In several embodiments, the various data includesflight data401 that may be provided by numerous sources, such as, for example, the aircraft's ACARS. In various embodiments, theaircraft data402 includes such information as aircraft equipment and tail numbers, andpublic references403 that includes industry information such as airport runway and schedule data from various sources such as the IATA or the FAA. As mentioned above, the various data is integrated to provide thefuel accounting system500 with the information necessary to validate fueling events, total fuel uplifted, and total fuel inventory.

Integration404 may be achieved in numerous ways in various embodiments, as will be apparent to one of ordinary skill in the art. For example, in one embodiment,integration404 is achieved via a queuing and routing program that receives and routes the various data to thefuel accounting system500. In another embodiment,integration404 is achieved by storing the various data on one device. In another embodiment,integration404 is achieved by simply connecting the various data storage devices via a communication network. Yet, in another embodiment,integration404 is achieved via a server that collects the data from the various data sources and provides the data to thefuel accounting system500.

In addition, in various embodiments, the fuel ticket data is provided to fuelaccounting system500 via a web-based front-enddata capture system405 that is used by an airline employee at the airport to enter the fuel ticket data. The employee simply calls up the web page over a communications network, such as the Internet, enters the fuel ticket data, and selects the “Save” button. In one embodiment, the web-based front-enddata capture system405 saves the fuel ticket information to a storage device that is in communication with thefuel accounting system500. In another embodiment, the web-based front-enddata capture system405 sends the fuel ticket data directly to thefuel accounting system500.

FIG. 5 shows a schematic diagram of afuel accounting system500 according to one embodiment of the invention. The fuel accounting system includes aprocessor60 that communicates with other elements within the computer system via a system interface orbus61. Also included in thesystem500 is a display device/input device64 for receiving and displaying data. This display device/input device64 may be, for example, a keyboard or pointing device that is used in combination with a monitor. Thesystem500 further includesmemory66, which includes both read only memory (ROM)65 and random access memory (RAM)67. The system'sROM65 is used to store a basic input/output system26 (BIOS), containing the basic routines that help to transfer information between elements within thesystem500. Alternatively, thefuel accounting system500 can operate on one computer or on multiple computers that are networked together.

In addition, thesystem500 includes at least onestorage device63, such as a hard disk drive, a floppy disk drive, a CD Rom drive, a DVD Rom drive, a USB flash drive, or optical disk drive, for storing information on various computer-readable media, such as a hard disk, a removable magnetic disk, a CD-ROM disk, or a DVD-ROM disk. As will be appreciated by one of ordinary skill in the art, each of thesestorage devices63 is connected to thesystem bus61 by an appropriate interface. Thestorage devices63 and their associated computer-readable media provide nonvolatile storage for a personal computer. It is important to note that the computer-readable media described above could be replaced by any other type of computer-readable media known in the art. Such media include, for example, magnetic cassettes, flash memory cards, digital video disks, and Bernoulli cartridges.

A number of program modules may be stored by the various storage devices and withinRAM67. For example, as shown inFIG. 5, program modules of thefuel accounting system500 include anoperating system80, a fuelingevent module600, a total fuel upliftedmodule700, and a totalfuel inventory module800. The fuelingevent module600, the total fuel upliftedmodule700, and the totalfuel inventory module800 control certain aspects of the operation of thefuel accounting system500, as is described in more detail below, with the assistance of theprocessor60 and anoperating system80.

Also located within thesystem500 is anetwork interface74, for interfacing and communicating with other elements of a computer network. It will be appreciated by one of ordinary skill in the art that one or more of the system'scomponents500 may be located geographically remotely from other system components. Furthermore, one or more of the components may be combined, and additional components performing functions described herein may be included in thesystem500.

Fueling Event Module

FIG. 6 illustrates a flow diagram of a fuelingevent module600 according to various embodiments of the invention. This flow diagram may correspond to the steps carried out by aprocessor60 in afuel accounting system500 shown inFIG. 5 as it executes the fuelingevent module600 in the system's500RAM memory67. Beginning atStep601, the fuelingevent module600 receives or accesses the fueling information for particular fueling events derived from a fueling agent. According to one embodiment, the fueling information is fuel ticket data key-entered into the system via a web page, as discussed above, in order for the fuelingevent module600 to gain access. In an alternative embodiment, the fuelingevent module600 receives or accesses the fueling information via a communications network (e.g., Internet or private network) or a transmission from the fuel dispenser truck through RF technology. In another embodiment, the fuelingevent module600 receives or accesses the fueling information either locally or remotely from various sources such as a different module, database, data warehouse, file, or some other storage device.

InStep602, the fuelingevent module600 receives or accesses the corresponding flight information for the fueling data. As previously discussed, various embodiments receive flight information that derives from flight data, aircraft data, and public references that has been integrated. In addition, fuelingevent module600 may receive or access this data in numerous ways. For example, according to one embodiment, the flight information is flight data received through various channels such as the aircraft's ACARS sending the data electronically or a flight data coupon that is manually entered into the system. In other embodiments, the fuelingevent module600 receives or accesses the flight information via a communications network (e.g., Internet or private network) or RF technology. In still other embodiments, the fuelingevent module600 receives or accesses the flight information through a legacy flight service system, scheduling system, or either locally or remotely from various sources such as a different module, database, data warehouse, file, some other storage device, or external source.

InStep603, the fuelingevent module600 determines whether one or more fueling events identified by the fueling information match to corresponding flight information. Various matching criteria may be employed as will be apparent to one of ordinary skill in the art. For example, according to various embodiments, this step is carried out by matching data such as origin airport, or flight number, or aircraft tail number, or gallons of fuel, or date. In addition, in various embodiments, tolerance levels may be established within the fuelingevent module600 to apply to the matching criteria. For instance, the fuelingevent module600 determines that a fueling event is valid if the origin airport, flight number and date is an exact match and the gallons of fuel are within ten gallons. Of course, other tolerance levels may be used depending on the degree of accuracy desired by the user.

If inStep603 the fueling event module determines that one or more fueling events are valid, the fueling events are released for further processing as shown inStep604. Likewise, any fueling events determined to be invalid are prohibited from further processing as shown inStep605. In various embodiments, further processing can have numerous meanings such as released to accounting for payment, batching for further approval, or making the fueling events available for reconciliation with fueling agent data. In turn, in various embodiments, prohibiting further processing can have numerous meanings, such as putting the fueling event on hold, printing a report to highlight the discrepancy, or deleting the fueling event from the system to ensure further processing is prohibited. One of ordinary skill in the art can envision many other measures encompassed in prohibiting further processing.

Total Fuel Uplifted Module

FIG. 7 illustrates a flow diagram of a total fuel upliftedmodule700 according to various embodiments of the invention. This flow diagram may correspond to the steps carried out by aprocessor60 in afuel accounting system500 shown inFIG. 5 as it executes the total fuel upliftedmodule700 in the system's500RAM memory67. Beginning atStep701, the fuel amounts for the fueling events released for further processing are summed to provide a total fuel amount data. In one embodiment, the released fuel amounts are supplied by the fuelingevent module600. In other embodiments, the released fuel amounts are entered either manually by an airline employee or automatically through electronic channels such as a communications network (e.g., Internet or private network) or received or accessed either locally or remotely from various sources such as a different module, database, data warehouse, file, or other storage device.

InStep702, the total fuel upliftedmodule700 receives or accesses an issued total data provided by the fueling agent. In various embodiments, the issued total data provided by the fueling agent can represent several different amounts such as the total amount of fuel dispensed by the fueling agent for a period of time or the fueling agent's ending inventory for a period of time. In addition, in various embodiments, the issued total data can be entered into the system in several different ways. The issued total data may be key-entered into the system via a web page, entered into the system electronically via a communications network (e.g., Internet or private network), or received or accessed either locally or remotely from various sources such as a different module, database, data warehouse, file, storage device, or the fueling agent's network or Web site.

Once the total fuel amount data has been determined and the fueling agent's issued total data has been obtained, the two amounts are compared, as shown inStep703. As will be apparent to one of ordinary skill in the art, numerous comparison models can be developed in various embodiments. For example, in one embodiment, the total fuel upliftedmodule700 receives or accesses the previous day's ending fuel inventory. This value may be stored on the system or received or accessed either locally or remotely from various sources such as a different module, database, data warehouse, file, storage device, or independent accounting system. The fuel uplifted module also receives or accesses and sums the fueling agent's bills-of-lading for the day. Again this information may be entered either manually or automatically into the system or received or accessed locally or remotely from various sources. The total fuel upliftedmodule700 calculates the ending fuel inventory for the day by taking the previous day's ending fuel inventory, adding the bills-of-lading summed total, and subtracting the released fueling events summed total. In addition, the total fuel upliftedmodule700 compares inStep703 the calculated value to the fueling agent's issued total data, which in this case represents the fueling agent's ending inventory, to see if the difference between the two values falls within a predetermined tolerance.

If a discrepancy is found inStep704 from the comparison inStep703, the total fuel upliftedmodule700 prohibits further processing of a least one of the released fueling events, as shown inStep705. Various embodiments can handle this result several different ways. In one embodiment, the total fuel upliftedmodule700 prohibits payment on at least one of the released fueling events. In another embodiment, a “red flag” is triggered such as putting at least one of the released fuel tickets on hold, automatically printing a report or sending an e-mail to an airline employee. Again, it should be apparent to one of ordinary skill in the art that a number of different mechanisms can be utilized to draw attention to the discrepancy.

If a discrepancy is not found inStep704 from the comparison inStep703, the total fuel upliftedmodule700 releases the fueling events for further processing, as shown inStep706. For example, in one embodiment, the fueling events are released to an accounting system to be reconciled and validated with distributed information from the fueling agent and issued for payment.

Total Fuel Inventory Module

FIG. 8 illustrates a flow diagram of a totalfuel inventory module800 according to various embodiments of the invention. This flow diagram may correspond to the steps carried out by aprocessor60 in afuel accounting system500 shown inFIG. 5 as it executes the totalfuel inventory module800 in the system's500RAM memory67. Beginning atStep801, the fuel receipts released from the fueling agent are summed over a specific period of time to provide a first total inventory amount data. In various embodiments, the fuel receipts are supplied by the fueling agent via several different ways such as over a communications network (e.g., Internet or private network), e-mail, facsimile, or mail. In addition, in various embodiments, the fuel receipts can be entered either manually by an airline employee or automatically through electronic channels such as a communications network (e.g., Internet or private network) or received or accessed either locally or remotely from various sources such as a different module, database, data warehouse, file, other storage device, or the fueling agent's network or Web site.

InStep802, the totalfuel inventory module800 receives or accesses the bills-of-lading over the period of time and sums the bills-of-lading in order to provide a second total inventory data. In various embodiments, the bills-of-lading are provided by the fueling agent while in other embodiments, the bills-of-lading are directly provided by the fuel supplier. In addition, in various embodiments, the bills-of-lading can be entered into the system in several different ways. For example, in various embodiments, the bills-of-lading may be received via a communications network, e-mail, facsimile, or mail. In addition, in various embodiments, the bills-of-lading may be key-entered into the system via a web page, entered into the system electronically via a communications network (e.g., Internet or private network), or received or accessed either locally or remotely from various sources such as a different module, database, data warehouse, file, storage device, or the fueling agent's/fueling supplier's network or Web site.

Once the first total inventory data and second total inventory data have been determined, the two amounts are compared, as shown inStep803. As will be apparent to one of ordinary skill in the art, numerous comparison models can be developed in various embodiments. In addition, various embodiments may utilize various tolerance levels. For example, the totalfuel inventory module800 compares inStep803 the calculated values to see if the difference between the two values falls within a predetermined tolerance of 50 gallons.

If a discrepancy is found inStep804 from the comparison inStep803, the totalfuel inventory module800 prohibits further processing of a least one of the supplier invoices for specified period of time, as shown inStep805. Various embodiments can handle this result several different ways. In one embodiment, the totalfuel inventory module800 prohibits payment on at least one of the supplier invoices. In another embodiment, a “red flag” is triggered such as putting at least one of the fuel receipts or supplier invoices on hold, automatically printing a report or sending an e-mail to an airline employee. Again, it should be apparent to one of ordinary skill in the art that a number of different mechanisms can be utilized to draw attention to the discrepancy.

If a discrepancy is not found inStep804 from the comparison inStep803, the totalfuel inventory module800 releases the supplier invoices for further processing, as shown inStep806. For example, in one embodiment, the supplier invoices are released to an accounting system for payment.
